This invention relates to road treating and surfacing apparatus and has for its primary object the provision of an organization of this character for effectively scratching the surface of a roadway and for leveling or planing the surface in advance of subjecting the soil to the action of a scarifier and for delivering fluid, such as oil or water, to a point beneath the surface of the soil during the scarification of the latter, whereby the top of the soil will be kept entirely free from those ordinary sloppy and oily conditions which heretofore have offered serious impediment to the work in progress and serious depreciation in the efficiency with which such work must ordinarily be conducted.

Another object of my invention is to provide apparatus of this character whereby portable tankers may be employed to effect a gravity feed of the oil treating fluid to the distributing mechanism which forms a part of my organization.

A still further object of my invention is to provide an apparatus of this character wherein the planer or road leveling means employed will effectively function to produce a track for the free passage of the supporting wheels of the structure.

A still further object of the invention is to provide novel and effective means for controlling the depth of penetration of the scarifying teeth and for raising the teeth entirely above the ground line at the option of the operator.

In carrying the invention into practice, use is made of a rectangular frame I which consists of a pair of longitudinal beams II, II, a front end beam 12, a rear end beam l3, and an operators platform It, the latter extendingfor a suitable distance from the rear cross beam l3 so as to satisfactorily accommodate an operator whose presence is desired when effecting actuation of the scarifier, The said longitudinal beams I I, H, are in the nature of runners, and same are preferably faced on their under surfaces with metallic wear strips I 5. A substantially V-shaped draft bar l6 finds pivotal connection at II at the forward portion of the said beams II, II, and as illustrated in. Figure 4 the said draft bar is provided with a cylindrical portion I8 which is adapted to enter a coupling sleeve l9 and to be detachably secured thereto by a bolt 20, the lat- 10 ter passing through the said sleeve l9 and through the said portion l8. The forward extremity of the sleeve I9 is provided with a clevis 2| which has removable connection with the hook 22 of a draft chain or similar well-known connection 23, the latter adapted to be coupled to a vehicle such as a tanker or the like, by means of which it is intended that the apparatus shall be drawn over the road surface under treatment.

In the forward portion of the frame I 0 is a scuffer or primary scarifier, and same preferably comprises a diagonaltoo-th bar 24- and a plurality of diagonal tooth bars 25, 25, the latter arranged in relative 'alinement and being positioned at the respective sides of the aforemen- 25 tioned bar 24 and arranged preferably at right angles thereto. The inner ends of the bars 25, 25, are rigidly connected at 26 to the middle portion of the bar 24 and their outer ends are fixedly connected at 21 to the beams I I. The extremities 30 of the bar 24 are fixedly connected at 28 to the beams II. The bars 24 and 25, 25, are of angle construction, and adjustable vertically in the horizontal flanges 28a of each thereof are teeth 29. These teeth may be satisfactorily confined in selected positions of vertical adjustment by U-shaped bolts 30, 30, which will find attachment at 3| to the vertical flanges of the said angle bars. These teeth project through the bottom of the frame I0 and each is formed with a forwardly and downwardly inclined penetrating point 32 adapted to penetrate the top surface of the soil for a suflicient depth to operate thereon preparatory to operation upon the soil by the scarifying mechanism at the rear end of the apparatus.

Immediately behind the scuffer or preliminary scarifier just above referred to and formed in the beams H, II, are alined longitudinally extending dirt passages 33. Extending crosswise of the frame structure I!) and passing through the alined passages 33 is a leveling or planing bar 34 which is preferably of rectangular form in transverse section, as shown in Figure 3 of the drawings. The front face of this bar is provided with a metallic facing strip 35 so as to prevent the bar 55 from undue abuse incident to constant contact therewith of the dirt. It will be noted upon reference to Figure 1 that the respective extremities of the bar 34 project for an appreciable distance beyond the sides of the frame I0. This is in order that tracks may be cleared for the passage thereover of the supporting wheels of the apparatus, as will be made clear as the description proceeds. From the construction of the bar 34 and the manner of correlating same with the openings 33, it follows that dirt gathered by the bar during the leveling or planing operation will find lateral exit through said passages.

Immediately in advance of the operators platform I4 is a scarifying mechanism 36, the same including a cross beam 31 adjustably supported at 38 to swing in a vertical plane so that it may assume either of the two positions shown, respectively, in full and dotted lines in Figure 3. Located preferably in a position above the platform I4 is a manifold or distributing head 39 having an intake branch 40 adapted to be connected in any suitable well known manner with a source of supply, such, for instance, as a tanker which I have hereinbefore referred to as a suitable means for drawing the apparatus over the roadway under construction. A flexible hose (not shown) may be led from the tanker to the said intake branch 40 of the said manifold. Extending in a forward direction from the manifold are fluid outlet pipes 42, and joined thereto and arranged in open communication therewith are hollow scarifying teeth 43. These teeth are in the nature of steel pipes, and they are preferably welded to the forward extremities of the pipes 42. These pipes project in a downward direction between the beams l I, I I, and to a point below the platform [4, I4, whereby, when they are elevated into the position shown in dotted lines in Figure 3, the lower roadway grooving ends 44 thereof will be entirely clear from the surface of the roadway, whereas when the said teeth are in the said full line position shown in Figure 3 the effective sharp lower ends thereof will be positioned where they will penetrate the road surface to such extent as may depend upon predetermined vertical adjustment of these teeth upon the supporting beam 31. At this point, it will be noticed that the said teeth are strapped to the beam 31 by U-bolts 45, and it is through their provision that means are herein provided for regulating the vertical adjustment of said teeth. In each of the pipes 42 is a controlling valve 41, by means of which the operator can regulate the amount of road treating fluid which is to be delivered into the soil from the lower extremities of the pipes 43. All of these valves are connected by links 49 to an oscillating bar 56. The said bar 50 may thus be actuated to simultaneously control the flow of fluid through the aforementioned scarifying teeth 43.

Angle plates carried by the longitudinal beams H, H, are disposed in the path of downward tilting movement of the cross beam 31, so as to retain the teeth 43 in their vertical scarifying positions shown in full lines in Figure 3. Winged guards 52 are secured to the cutting ends of said teeth 43 and are designed to penetrate the soil and to act upon same to prevent clogging of the teeth when the machine is in action.

The wheel base of my machine consists of an axle 53 journaled in the beams H, II, the same provided at its ends with crank arms 54 whose free end portions revolubly support the ground wheels 55. The axle 53 carries a worm gear 56 which meshes with a worm 51 at the lower end of a controlling shaft 58. The said shaft 58 extends upward and rearwardly to a point above the right hand end of the apparatus platform l4 and same is provided with a crank handle 59 adapted to be manually actuated. It has been stated that the teeth 43 can be adjusted vertically in order that the extent of their penetration into the soil may be initially determined. By this is meant the extent of their penetration when the wheels 55 are in the extreme elevated full line positions shown in Figures 2 and 3. It manifestly follows that by reason of the means employed herein for changing the positions of wheels 55 relatively to the lower faces of the beams H, H, it is possible to govern the degree of pressure exerted there against and also to control the extent of penetration of the said teeth 43 into the ground. In other words, it is possible to tilt the rear portion of the machine vertically without causing the f or ward portion of the machine to leave the surface of the roadway under treatment. This permits also the regulation of the action of the teeth 23 upon the ground to control the scuffing effect thereof as desired. When the teeth 43 are tilted in their dot-and-dash positions shown in Figure 3 and the wheels 55 adjusted to the positions where their tread surfaces are below the lower surfaces of the beams II, II, as shown by the dot-and-dash lines, Figure 3, both sets of teeth 29 and 43 are renderd inactive relatively to the 3 ground.

In operation, let it be assumed that the machine is being drawn over a roadway and that both the scufling teeth 29 and the scarifying teeth 43 cccupy the positions shown in Figure 3. In conse- 3 quence thereof, the surface of the roadway will be gouged or scuffed by the teeth 29, the action of which said teeth is succeeded by the leveling or planing bar 35. Dirt collected by the said bar is deflected laterally and outwardly and is compelled to find exit from between the beams H, II, by way of the openings 33. Following the planing of the soil as just referred to, the scarifying teeth 43 act upon the ground beneath the top surface of 7 the roadway and to a depth appreciably in excess of that of the penetration of the teeth 29 and at the very depth of said penetration of said teeth 43, a soil treating fluid such as oil or water is effectively administered to the soil where it will not unduly muss or make sloppy the said top surface. Whenever the occasion necessitates, a rod or the like may be projected downwardly into the teeth 43 to clear same of foreign matter so that a free outlet is provided for the flow of fluid from said teeth.

The manifold 39 and the fluid feeding pipes which extend forwardly therefrom serve to overbalance the teeth 43 when the lower ends of the latter are out of the ground and to move this part of the organization to the said dot-and-dash 60 line position shown in Figure 3, at which time the pipe 40 to which the supply hose or the like is adapted to be connected is received in a slot 58a in the operators platform l4. By means of a forwardly extending cable 59a whose rear end is attached to one of the teeth 43 near the top thereof, the teeth 43 can be manually thrown into their operative scarifying positions by actuating said cable at the drivers seat of the tanker from which the machine is drawn.

In the form of my invention shown in Figures 7 and 8 of the drawings, compressed air in a tank 60 upon the operators platform 14 is connected with a distributing manifold B! by a flexible tubing 62. The said manifold opens-at 63 intothe 7 upper ends of the respective hollow teeth 43a of a scarifying mechanism 44a. Below the point of entrance to each of said teeth, the manifold is provided with a downwardly opening check valve 64 which may be of any suitable well known construction adapted to be opened by the force of air pressure from the tank 60. The oil or fluid distributing manifold 39a is substantially the same as the manifold 39 first above referred to, and. it will be observed that its point of entrance to the respective hollow teeth 43a is located beneath the manifold 6| so that when air under pressure is discharged downward into the upper ends of said teeth, suction will be induced at the point A so as to accelerate the movement of the fluid from the manifold 38m and insure free passage thereof in the direction of the lower soil penetrating ends of said teeth. In this manner, it manifestly follows that the soil treating fluid may be more effectively distributed into the soil as the machine is normally drawn over the surface under treatment or construction. Whenever it may be necessary to clean the bores of the teeth, the valve mechanism 63 at the distributing manifold 3911 can be manually actuated to close the teeth against the discharge of fluid thereinto, at which time air from the tank may be forced into the teeth and any obstructions contained therein will be rapidly expelled from the lower ends thereof.

Air may be supplied to the tank 60 through a compressor 64a carried by the platform I4. Said compressor is operatively connected at 65 to a power plant 66, such as an internal combustion engine.

I do not wish to be limited to the form of scarifying mechanism herein shown, and it is my intention to substitute therefor any suitable well known form of scarifier, just so long as provision is made in company therewith to distribute the soil treating fluid to the soil at a point at the effective soil digging or scarring surfaces of the im- 5 plement employed.

What is claimed is:

1. In a fluid distributing mechanism for road building machines, a fluid intake and discharge manifold having a longitudinal series of spaced 10 apart soil penetrating pipes; a vertically adjustable portable frame on which the manifold is mounted to tilt about a horizontal axis transversely of the frame to vertically dispose the pipes in positions to penetrate the soil when lowering 5 the frame and retract therefrom when raising the frame; and means for adjusting the frame for the purpose stated and for controlling the extent of said adjustment to regulate the depth of penetration of the pipes into the soil. 20

2. In a fluid distributing mechanism for road building machines, a fluid intake and discharge manifold having a vertical series of fluid distributing pipes depending therefrom; means for controlling the discharge of fluid from the pipes; 25 a vertically adjustable portable frame on which the manifold is mounted; means for raising and lowering the frame to enable the pipes to pierce the soil when lowering the frame and retract from the soil when raising the frame; a source of fluid supply with which the manifold is connected to enable fluid to pass to the manifold from the source; and means for imposing pressure upon the fluid to force injection of the fluid into the soil when the frame is lowered.
